Question: Particles of charge +65, +48, and ?95 ?C are placed in a line (Figure 1) . The center one is L = 35cm from each of the others.
Part A: Calculate the net force on the left charge due to the other two. Enter a positive value if the force is directed to the right and a negative value if the force is directed to the left.
Part B: Calculate the net force on the center charge due to the other two. Enter a positive value if the force is directed to the right and a negative value if the force is directed to the left.
Part C: Calculate the net force on the right charge due to the other two. Enter a positive value if the force is directed to the right and a negative value if the force is directed to the left.
B. the MIDDLE charge experience repulsive force F due to the
first and attractive force F due to the right charge. so the net
foce is F = F1- F2 = 1/40
[ Q1Q2 - Q2Q3] / d
2
F = 9x109 [ 65x48 - 48x95] x10-12 / 352 = 10.579x10-3 N
A.. the left charge experience repulsive force F1 due
to the middle and attractive force F2 due to the right
charge. so the net force F = 1 / 0
[ Q1Q2 - Q2Q3] / d
F = 9x10 [ 65x48/352 - 65x95/702 ]x10-12 = 11.518x10-3 N
C. force experienced by the third charge is attractive force F1by both first and F2 bymiddle
charge.so the net force F = F1 + F2 =
1/40
[65x95 / 702 + 48x95/352 ] 10
-12
= - 44.84x10-12 N
